There are so many stories about people who hate each other at first and then fall in love, and I was concerned that this would be rather trite. I was pleased that it managed to spin June and Oliver's story a slightly different way, and that the bulk of the book was not about them pining for each other only to fall in love and have something rip them apart, like so many other books are. The inclusion of music will add appeal to many readers.
I've always been a big fan of teen literature from the 1950s, and Shuffle, Repeat had some of the same qualities-- up-to-the-minute descriptions of current trends in fashion, technology and social mores set against the unchanging angst that is senior year! Put this one in a time capsule as a perfect description of high school life in 2016!
This is definitely a young adult book, and while there isn't a lot of drinking or any instructional sexual activity, there is plenty mentioned, and very sensitive readers might want to try books by Sarah Dessen or Jennifer E. Smith instead.
